Acute-onset amnesia: transient global amnesia and other causes.

Pract Neurol 2022 Jun 3;22(3):201-208. Epub 2022 May 3.

Department of Brain Sciences, Imperial College London, London, UK.

Acute-onset amnesia is a dramatic neurological presentation that can cause considerable concern to both patient and clinician. The patient typically presents with an inability not only to retain new memories but also to access previously acquired memories, suggesting disturbance of hippocampal function. Transient global amnesia (TGA) is the most common cause of acute-onset amnesia, and is characterised by a profound anterograde and retrograde amnesia that typically lasts for up to 24 hours.

The remains of the day: neuropsychological findings in postacute transient global amnesia.

J Neurol 2022 Apr 8. Epub 2022 Apr 8.

Department of Neurology, University Medical Centre Mannheim, Medical Faculty Mannheim, Heidelberg University, Theodor-Kutzer-Ufer 1-3, 68135, Mannheim, Germany.

Introduction: Current clinical diagnostic criteria of transient global amnesia (TGA) require the episode to completely resolve within 24 h. Small case series investigating the neuropsychological profiles obtained during the first days after TGA are inconclusive, with some suggesting the persistence of memory deficits.

Methods: In this retrospective observational study, neuropsychological data of 185 TGA patients obtained during the first days following an attack were analysed. Read More

Transient global amnesia: Model, mechanism, hypothesis.

Andrew J Larner

Cortex 2022 04 31;149:137-147. Epub 2022 Jan 31.

Cognitive Function Clinic, Walton Centre for Neurology and Neurosurgery, Liverpool, United Kingdom. Electronic address:

Transient global amnesia (TGA) is a rare but well-described neurological disorder characterised by an acute self-limited episode of dense anterograde amnesia with retrograde amnesia of variable extent. Although the clinical phenomenology, neuropsychology, neuroimaging, prognosis, and precipitating and predisposing factors of TGA are well described, the pathogenesis is not currently understood. Existing proposals - epileptic seizure, stroke or transient ischaemic attack, migraine aura - all have shortcomings. Read More

Hippocampal subfield involvement in patients with transient global amnesia.

J Neuroimaging 2022 Mar 2;32(2):264-267. Epub 2022 Feb 2.

Department of Neurology, Medical Faculty Mannheim, Heidelberg University, Mannheim, Germany.

Background And Purpose: Transient global amnesia (TGA) is a rare neurological disorder causing a transient disturbance of episodic long-term memory. Its etiology remains yet to be identified; the only consistently reported findings in patients with TGA are small hyperintense lesions in the hippocampus on diffusion-weighted magnetic resonance imaging (DWI). The aim of this study was to define whether these lesions are subfield specific, as suggested previously. Read More

Transient Global Amnesia.

Am Fam Physician 2022 01;105(1):50-54

Medical University of South Carolina, Greenwood, SC, USA.

Transient global amnesia (TGA) is a clinical syndrome characterized by anterograde amnesia, mild retrograde amnesia, and confusion up to 24 hours. Most commonly seen in patients older than 50 years, TGA results from the temporary impairment of short-term memory formation. Clinically, patients have time disorientation and often ask repeated questions regarding the day's events. Read More

Recurrent amnesia caused by early seizures after hippocampal infarction: a case report.

BMC Neurol 2022 Jan 10;22(1):18. Epub 2022 Jan 10.

Klinik und Poliklinik für Neurologie, Kopf- und Neurozentrum, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Background: We report the case of a patient with recurrent episodes of disturbed memory suggestive of transient epileptic amnesia, and a focal hippocampal lesion typically associated with transient global amnesia. We argue how careful consideration of clinical, electrophysiological and imaging findings can resolve this apparent contradiction and lead to a diagnosis of early symptomatic post-stroke seizures that links brain structure to function in a new, clinically relevant way.

Case Presentation: A 70-year-old patient was identified in clinical practice in our tertiary care centre and was evaluated clinically as well as by repeated electroencephalography and magnetic resonance imaging. Read More

Stroke Mimics in the Acute Setting: Role of Multimodal CT Protocol.

AJNR Am J Neuroradiol 2022 02 30;43(2):216-222. Epub 2021 Dec 30.

Department of Neuroradiology (A.C.), Inselspital Bern, University of Bern, Bern, Switzerland.

Background And Purpose: Ischemic stroke can be mimicked by nonischemic conditions. Due to emphasis on the rapid treatment of acute ischemic stroke, it is crucial to identify these conditions to avoid unnecessary therapies and potential complications. We investigated the performance of the multimodal CT protocol (unenhanced brain CT, CTA, and CTP) to discriminate stroke mimics from acute ischemic stroke. Read More
